Kuriimu means
cream.
Okashi tsukurio hajimeru mae ni junbi means;
Order of food preparation for the cake's structure., as far as I can tell.
That might not be the exact meaning, but it's the best I could do.
Also, when you see a word like
kuriimu, usually you can just say it out loud, and hear that that it sounds almost exactly like the English word,
cream, and tell by that.
